Can cats or dogs eat seaweed (nori)?

Cats: No conclusions yet · Dogs: Be careful — Seaweed sold as food, such as nori, crispy seaweed. Give your dog a small amount occasionally. It is quite high in iodine and sodium. Those with thyroid problems or heart disease should avoid them. Do not feed seaweed collected from the beach because it contains dangerously high salt levels. As for cats, there is no direct information from veterinarians. Give a small amount without seasoning. If you eat beach seaweed or experience any unusual symptoms, you should see your veterinarian immediately.
